Solving Quadratic Equations by Completing the Square
Solving Quadratic Equations by Completing the Square Solving quadratic equations by completing the square is overpowered by an "offspring" of this process, namely, the quadratic formula. The quadratic formula was derived by completing the square on a quadratic equation. Once the quadratic formula was derived, it was no longer necessary to use the process of completing the … [Read more...] about Solving Quadratic Equations by Completing the Square
Solving Quadratic Equations with Complex Roots
Solving Quadratic Equations with Complex Roots When the roots of a quadratic equation are imaginary, they always occur in conjugate pairs. A root of an equation is a solution of that equation. If a quadratic equation with real-number coefficients has a negative discriminant, then the two solutions to the equation are complex conjugates of each other. (Remember that a … [Read more...] about Solving Quadratic Equations with Complex Roots
